How old is your daughter? My daughter was 14 ish when she was dianosed as having a slight curvature of her spine causing one leg to be shorter than the other. She'd been complaining of painful back, legs and feet for a long time before they found out what the problem was. She's in her 30s now and still get pain occaisionally, sciatica being the main problem. She finds that keeping her weigh down is a real help. If your daughter's pain is too bad take her back to the specialist. Hope she'll be ok though xx
